A ball of mass mb and volume V is lowered on a string into a fluid of density ρf. (Figure 1) Assume that the object would sink to the bottom if it were not supported by the string.
What is the tension T in the string when the ball is fully submerged but not touching the bottom, as shown in the figure? Express your answer in terms of any or all of the given quantities and g, the magnitude of the acceleration due to gravity.

Archimedes Principle - Upward Tension Additional Force As shown in the above figure, a solid object has a density of 1200 kg/m3 and a volume of 7.80x10^-5 m3. It is lowered on a string into water and completely submerged without touching the container. The density of water is 1000 kg/m3. Keep 3 decimal places in all answers. (Don't use scientific notations.) Without the string, would the solid object sink in water or float in water?...

Energy, Force, and Kinematics A smooth frictionless incline is d meters in length and is at an angle of theta > 30 degree with respect to the ground. A block of mass mA = m starts from rest at the top of the incline (see figure). It is connected to a lighter mass mB = m/2 by a massless string that stays taut throughout the block's descent. In terms of the given quantities m, theta , and acceleration due to...

A ball of mass,m, is attached to a string of length,l . It is being swung in a vertical circle with enough speed so that the string remains taut throughout the ball's motion.Assume that the ball travels freely in this vertical circle with negligible loss of total mechanical energy. At the top and bottom of the vertical circle, theball's speeds are vt and vb, and the corresponding tensions in the string are Tt and Tb. Tt and Tb have magnitudes...
